Corsair CS Series Modular 650W Power Supply Review

Introduction and Features

Corsair's new CS Series Modular PSUs include four models; the CS450M, CS550M, CS650M and CS750M. All of the power supplies in the CS Series feature modular cables, high efficiency (80 Plus Gold certified) and quiet operation. In addition, Corsair continues to offer a full line of high quality power supplies, memory components, cases, cooling components, SSDs and accessories for the PC market.

Here is what Corsair has to say about their CS Series Modular PSUs: “The CS Modular Series is designed for basic and midrange PCs, but offers features and performance traditionally reserved for higher-end models. 80 Plus Gold efficiency and a thermally controlled fan ensure quiet operation and lower energy use, and the modular, detachable cable set makes installations and upgrades faster and better looking.”

And, like all Corsair power supplies, CS Series Modular is built with high-quality components and is guaranteed to deliver clean, stable, continuous power.”
